True Digital Signal Processing delivers unparalleled radar performance
Friday 09 January 2009 - Extending the massive leap in radar technology already available from Raymarine’s HD (High Definition) Digital radar, the company is now showing the next generation of digital radar, Super HD Digital, at London International Boat Show 2009.
With a choice of 4kW or 12kW of power and the option of 48” or 72” open array scanners, Super HD Digital radar technology offers radar performance superior to that of a 25kW analogue radar and uses 25% or less of the power that the same analogue radar would need to achieve the same result. The new Super HD Digital technology effectively doubles the antenna size resulting in significantly superior performance, processing and target detection.
This evolutionary breakthrough has been achieved thanks to Raymarine’s development and unique handling of Digital Signal Processing. Using true ‘front end’ digital technology, Raymarine has improved target detection by eliminating virtually all unwanted noise and thereby enhancing the detection of small targets. By processing 16,000 levels of data digitally (typically around four levels of data are processed on non-digital radars), this provides leisure boaters with the type of radar images and detailed accuracy only previously available on commercial vessels. Displayed on the latest G Series, with options to use 256 colours on graded target returns, Raymarine say it’s like comparing images from a black and white TV to the image available from a high definition colour TV.
Raymarine’s new Super HD Digital uses echo characterisation rather than amplitude of signals to produce outstandingly clear images. With a huge dynamic range of 90+ dB, it ensures that all possible targets are identified and displayed. In addition, a key benefit of Super HD Digital radar is its ability to work in dual range mode. With its unique method of processing two distinct ranges of data, Raymarine’s Super HD Digital dual scanner interleaves long and short range spokes on each scan, effectively giving users two separate and independently controlled radars in one unit. The fact that this process happens within one sweep means operators can see and control both long-range and short-range displays at the same time secure in the knowledge that signal returns are fast and accurate giving extra clarity to target detection and display.
Another useful feature for users available from Super HD Digital is the multi-level colour target display. This means that targets with different echo return strengths - such as a vessel in front of a rocky island, or rain over vessels or navigational buoys – are shown on the display in different colours, for example it is possible to see navigational buoys, vessels and weather systems all at once and with great clarity. Fully SeaTalk network compatible, the high resolution and clarity of the new Super HD Digital radar is particularly impressive on the new ultra bright G Series monitors, and multi-function E series brilliant sunlight viewable screens.
Using Raymarine’s new thin wire connections, the Super HD Digital radars are easy to install thanks to the external waterproof connector. Operating using 10.3 to 32V DC power, the system comes complete with an external voltage converter.
Intuitively simple to use, the Super HD Digital radars offer a choice of auto modes – for use in coastal, harbour, and offshore areas as well as a setting specifically for buoy detection.
Raymarine’s new Super HD Digital open array radars will retail at £3965 ex VAT for a 4kW 48” open array up to £5340 ex VAT for the 12kW 72” open array.
